Behind the Scenes of 'Spider-Man: Turn Off the Dark'

May 19, 2011— -- It's the most expensive musical in Broadway history, "Spider-Man: Turn Off the Dark," and perhaps the most criticized. The opening has been delayed six times, five cast members have been injured along the way -- one almost died.

Yesterday, we had the opportunity to talk to U2's Bono and the Edge who wrote the score. It is their first television interview since the show opened for previews last November and director Julie Taymor, the show's creative mastermind, was fired.

They told us they agreed with much of the criticism of the show but feel the new version works: "It's 80 percent there." It will be 100 percent, they say, by opening night June 14.

Tune into "Nightline" tomorrow at 11:35 p.m. ET/PT for an extraordinary back-stage pass. For a sneak preview, that photo above shows the three of us posed in the machine that turns actor Norman Osborn into the Green Goblin!
